A series of self-immolative linkers containing a thiol-reactive group at one end and a hydroxyl- or amine-reactive group at the other were prepared. The utility of these reagents for preparations of bioconjugates was explored by reacting the linkers with appropriately functionalized model drugs and peptides. Degradation studies of a series of conjugates with different linkers reveal that the structure
New compounds having the formula ##EQU1## wherein R.sub.1 represents a hydrocarbon moiety having from 1 to 7 carbon toms, R.sub.2 is hydrogen, methyl or ethyl, and R.sub.3 is hydrogen, formyl or acetyl. The compounds are useful in the preparation, modification and intensification of a great variety of flavor and perfume compositions.

A description is given of precursor compounds of sweet taste receptor antagonists for the prevention or treatment of disease, in particular for the prevention or treatment of Type 2 diabetes.
A description is also given of uses of these precursor compounds and edible compositions, preparations for nutrition or pleasure or semi-finished products and pharmaceutical preparations, containing such precursor compounds.
Disclosed are sulfide-based compounds which are a product of a Michael addition reaction between a sulfur-containing donor group and an unsaturated hydrocarbon moiety. The sulfide-based compounds may be used in compositions and methods for inhibiting corrosion.
